Ample research has shown that intensive applied behavior analysis (ABA) treatment produces robust outcomes for individuals with autism spectrum disorder (ASD); however, little is known about the relationship between treatment intensity and treatment outcomes. The current study was designed to evaluate this relationship. Participants included 726 children, ages 1.5 to 12 years old, receiving community-based behavioral intervention services. Results indicated a strong relationship between treatment intensity and mastery of learning objectives, where higher treatment intensity predicted greater progress. Specifically, 35% of the variance in mastery of learning objectives was accounted for by treatment hours using standard linear regression, and 60% of variance was accounted for using artificial neural networks. These results add to the existing support for higher intensity treatment for children with ASD.
大量研究表明，强化应用行为分析（ABA）疗法能为自闭症谱系障碍（ASD）患者带来显著疗效；然而，对于治疗强度与治疗效果之间的关系却知之甚少。本研究旨在评估这种关系。研究对象包括726名年龄在1.5至12岁之间、接受社区行为干预服务的儿童。结果表明，治疗强度与学习目标掌握程度之间存在密切关系，治疗强度越高，进步越大。具体而言，使用标准线性回归分析，学习目标掌握程度的35%的变异可由治疗时长解释，而使用人工神经网络时这一比例为60%。这些结果进一步支持了对自闭症谱系障碍儿童进行高强度治疗。
